np. You can assume dc but what you drew is correct as wellone more question sorry
if they don't specify in the question whether the source is ac or dc then is this how you draw it??

Guys I need your help in a Chemistry Paper 6 question
There was this question my friend gave me. It goes like this:
You have two metals- metal A and metal B. Hydrogen gas is given out when both metals react with Sulphuric acid. Plan an experiment to find out which metal is more reactive
The answer I wrote was: Take sulphuric acid in a beaker and add Metal A to it in excess. Filter out the excess Metal when effervescence stops. Add Metal B to the filtrate and check for a rise in temperature. If there is a rise, then Metal B is more reactive as it'll displace Metal A. If not, then Metal A is more reactive.
Is my answer correct? Will I get the full 6 marks?
It just came in the ExamWhy does this question seem so familiar?
Precisely we can't discuss it yetIt just came in the Exam
Take reading at the edges of the cylinder r1 and r2 and get their average .. this shoud be 10 cm .http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Physics (0625)/0625_s08_qp_6.pdf Question 1 b Silly ain't it? Lol I dunno well what i would write is know the length of the Cylinder and place it accordingly
ANYONE ?Please jun012 v.61 no.1 a
Sorry have no idea But i still its just a guess that's the reason in the marking scheme they have given a wide rageANYONE ?
Ok i found something else: graph lines should be neat, thin and a good fit (if there is scatter of points they should lie either side of the line{in a rough way!! }). Straight lines should FILL the page (even beyond the range of points) so that any gradient calculation can use the largest Dy and Dx. Students should understand why! (Dy is a measurement.)Should we extrapolate graphs for physics in alternative to practical?
I think thresholds are decided after all exams are markedWhat is the average mark required to get an A* in Chemistry out of 180 (the total)? I know it is a silly question but any idea?
T is the heighthttp://papers.xtremepapers.com/CIE/Cambridge IGCSE/Physics (0625)/0625_s08_qp_6.pdf question 1 d (i) how TO MEASURE t and where is it?
